AbstractA nanosecond repetitively pulsed microplasma generated between two tungsten electrodes in a pin-to-pin configuration is used as a supply of charged species to produce an electrohydrodynamic phenomenon when placed near a DC-biased electrode. We employed high-frequency particle image velocimetry in order to study the produced flow. The generated flow velocities are around 2 m • s-1 with a deposited average power on the order of 1 W. The velocity and the geometry of this flow are discussed as well as the impact of the repetition frequency and the DC field. We also explain the impact of each microplasma event on flow modification.
